Buying Considerations
When selecting the Delixi DZ47s 4P C 13A circuit breaker, consider these critical factors:
Current Rating Selection: Ensure the 13A rating matches your circuit's maximum load requirements. For motor applications, account for starting currents that may exceed the nominal rating.
Tripping Characteristic: The C-characteristic (5-10x rated current) is suitable for circuits with moderate inrush currents. For purely resistive loads, consider B-characteristic breakers, while D-characteristic is better for high inrush applications.
System Compatibility: Verify your electrical system requires 4-pole protection. For single-phase applications, 2-pole circuit breakers may be more appropriate and cost-effective.
Breaking Capacity: The 6KA rating is adequate for most commercial and light industrial applications. For facilities with higher available fault currents, consider breakers with 10KA or higher breaking capacity.
Panel Space: Ensure adequate space in your distribution panel for the 4-pole configuration, which typically occupies 4 modular spaces (4 x 18mm).
Frequently Asked Questions
Q: What is the difference between B, C, and D characteristic circuit breakers?
A: B-characteristic (3-5x In) is for resistive loads, C-characteristic (5-10x In) for moderate inrush currents, and D-characteristic (10-20x In) for high inrush applications like motors and transformers.
Q: Can I use this 4-pole breaker for single-phase applications?
A: While technically possible, it's not recommended as it wastes panel space and cost. Use appropriate 2-pole circuit breakers for single-phase systems.
Q: What maintenance is required for miniature circuit breakers?
A: MCBs require minimal maintenance. Regular visual inspection for damage, periodic testing of trip functionality, and ensuring proper torque on connections are recommended. The Delixi DZ47s is maintenance-free under normal operating conditions.
